Yep..... been making a LOT of calls about this reciently. My considerations were:
Pirelli P-Zero Corsa
Pirelli P-Zero Corsa System
Toyo R888
Yokohama A048
Michelin Pilot Sport 2 Cup
All in 225/45/R18
The advice I have managed to piece togeather is the following:
1) Pirelli P-Zero Corsa System is not recommended best stick with Corsa.
2) Corsa is great for DRY and cold/medium temperature conditions where the track is not to twisty (generating heat) as they go "off" quickly after only a few laps.
3) Toyo R888 - Great Track/race Tyre very compromised on the road, but sold out and extremely hard to get hold of in the required size.
4) Yokohama A048 - basically a very good compromise tyre, good on track - Not quite as good as the Pirelli in the cool but better in all other conditions including rain. Also good performing road tyre.
5) Michelin Pilot Sport Cup - expensive, not good in wet especially on the road. On dry day very quick not quite as much longevity as Yoko's.
Overall recommendation was for the Yoko's.
I did some research on purchasing Yoko's (basically phoned every re-seller, distributor and Yoko themselves in the UK and found that Yokohama A048 - 225/45/18 are on back order and a delivery of only 20 units are due into the UK in late July. 8 of which have already been sold.
The best advice I recieved from any person was from Micheldever Tyre Services - Race Support department - The guys who support several Porsche cup cars and other GT/Britcr/racing teams. I spoke to the guy who actually does the tyre testing and seemed to have real hands on knowledge rather than catalogue blurb.
